Hey all! I wrote a function that will come in handy when printing tables in Lua. Normally, when you call print on a table, it is first tostring-ed into a memory address and looks something like table: 000002074CD2C070. How unhelpful! If only there was a better way… I’ve created a function, repr, that works like Python’s repr. It’s short for representation, and it returns a nice

jagt/pprint.lua: yet another lua pretty printer, lua exposes pprint table with two other functions: pprint() : pretty print arguments, each argument starting on a new line. pprint.pformat(obj It makes the tostring- function act differently if a table has no corresponding metafunction: Usage: print uses tostring by default, so: > print{1,2,'3'} --outputs: table: 0x002cc2c8 { 1, 2, "3" } This is

LUA-skriptet “script_time_owfs.lua” körs varje minut i Domoticz och lägger till alla värden i sk dummie-devices i Domoticz. 075, print ( "Onewire hub reconfigured" ) 103, -- Implode a string into a table using delimiter 

For string keys only, Lua provides an alternate syntax, where t.foo is exactly equivalent to t["foo"]. I believe that recent versions of ngx_lua have the problem that if you pass a table to ngx.print() they segfault. I say believe, because the builds I run have a lot of code that I've been hacking recently, so there may be a bug in that, but I tried back to version 2.0 of ngx_lua and it went away.

Thanks, that's what i was looking for, I just had forgotten how to do this, and couldnt seem to find it … 2020-03-08 Lua is commonly described as a "multi-paradigm" language, providing a small set of general features that can be extended to fit different problem types.Lua does not contain explicit support for inheritance, but allows it to be implemented with metatables.Similarly, Lua allows programmers to implement namespaces, classes, and other related features using its single table implementation; first Lua functions. table.concat - Concatenates table items together into a string table.foreachi - Applies a function to each item in a numerically-keyed table table.getn - Returns the size of a numerically-keyed table table.insert - Inserts a new item into a numerically-keyed table table.maxn - Returns the highest numeric key in the table table t = { { str = 42, dex = 10, wis = 100 }, { str = 18, dex = 30, wis = 5 } } mt = { __lt = function (k1, k2) return k1.wis < k2.wis end } -- apply metatable to all tables inside our table for _, v in ipairs (t) do setmetatable (v, mt) end -- for table.sort (t) table.foreachi (t, function (k, v) table.foreach (v, print) end ) - … Lua was first created to be used on embedded systems, the idea was to have a simple cross-platform and fast language.
